title: [I-131 uptake in renal cyst: a false positive result].
abstract: We present the case of a 60-year old male with a follicular pattern of multifocal invasive papillary thyroid carcinoma who had undergone total thyroidectomy. During post-surgical follow-up with I-131 scan, a I-131 deposit was observed in the upper left hemiabdomen. Due to suspicion that it could be a metastasis, an ultrasound and CT scan were performed, with the subsequent diagnosis of a left simple serous renal cyst. Once confirmed, drainage was performed under ultrasound control, obtaining I-131 in the analysis of its content.
